9.5 Boost Regulator
The boost regulator boosts the input voltage to the regulated output voltage that drives the LED anodes. The MSL3080 boost regulator
uses an external MOSFET switch and current sense resistor, allowing a wide variety of input/output voltage combinations and load
currents. The boost regulator switching frequency is 625kHz. Switching frequencies of 350kHz, 500kHz, 750kHz, 875kHz and 1Mhz are
also available; contact the factory for information.
